AIM To determine whether pharmacological mydriasis leads to a significant difference in interobserver agreement of optic disc measurement compared with examination without mydriasis. METHOD A cross sectional study was performed with a pair of observers examining the optic disc of two randomised groups of patients, one group before diagnostic mydriasis, and the other afterwards. Horizontal and...

Two intraocular phenomena folloiuing sympathetic denervation—degeneration mydriasis and degeneration hyperemia of the iris—were studied in conscious albino rabbits. The superior cervical ganglion was removed on one side (denervation) and the preganglionic sympathetic trunk was cut on the control side. Mydriasis and hyperemia toere judged by comparing the two eyes. Mydriasis started about 14.5 h...

Hourly measurements of the transient mydriasis and intraocular pressure decrease after right cervical ganglionectomy and left cervical sympathotomy were simultaneously performed in conscious rabbits. The times of onset of these phenomena after the denervation were 14.51 0.21 hr. (n = 8) and 18.71 ± 0.78 hr. (n = 7), respectively. Their duration values were 18.01 ± 0.89 hr. (n = 8) and 18.81 ± 1...

This study is to identity the clinical characteristics of mydriasis derived from nebulized ipratropium bromide in neurosurgical patients. We presented 3 patients with inhalation of ipratropium bromide associated mydriasis and reviewed the pertinent literature. Mydriasis was caused by nebulized ipratropium bromide leak from the mask into ipsilateral eye. When the medication was discontinued in t...

Introduction Serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressants thanks to overall safety and tolerability spectrum. However, they can cause different side effects that not all of them well identified. Objectives We intend clarify clinical presentation mydriasis caused by Escitalopram. Methods Reporting case a patient suffering major depressive disorder, prese...

BACKGROUND Laser therapy has been the gold standard treatment for retinopathy of prematurity (ROP), while intravitreal bevacizumab (IVB) is reported to be of significant benefit for zone I ROP. A problem with laser therapy is that it is difficult to administer in ROP patients with severely dilated tunica vasculosa lentis and poor mydriasis. However, although IVB treatment has been performed in ...

Purpose. To compare the effects of physiologic versus pharmacologic pupil dilation on anterior chamber angle (ACA) measurements obtained with spectral domain optical coherence tomography (SD-OCT). Methods. Forty eyes from 20 healthy, phakic individuals with open angles underwent anterior segment OCT imaging under 3 pupillary states: (1) pupil constricted under standard room lighting, (2) physio...
